In this paper, we study the reflected solutions of one-dimensional backward stochastic differential equations driven by *G*-Brownian motion (RGBSDE for short). The reflection keeps the solution above a given stochastic process. In order to derive the uniqueness of reflected *G*-BSDEs, we apply a \martingale condition" instead of the Skorohod condition. Similar to the classical case, we prove the existence by approximation via penalization.
